Born in 1927 in Villa Guardia (COMO) - Italy. After graduating from  the “Accademia di Belle Arti” at Brera, Milan in 1948, he continues his studies there and receives his Diploma in Sculpture, in 1952. That same year he obtains his first major commission for sculptures and decorations for the baroque palace of the Opera “Der Rosenkavalier” at the Scala Theatre in Milan. In 1966 he moves to Vancouver (Canada) where he begins a long personal artistic study and research involving the use of new materials and techniques. It is thanks to  this dependence to new materials such as steel,, fibreglass, plastic, copper and others that Trinca experiments pop art for some time. His artistic journey produces elements of abstract art through a process of elimination of those non-essential figurative elements. Fascinated by the art of the native Indians and Esquimo, Trinca’s next step is to reduce  the form to its bare essence and create works full of intrinsic symbolic contents and  singular expressive power.  His principal and recurring theme is that of centrality, representing in synthesis the human condition where  materialism and spirituality harmoniously join to find their natural balance. During the  80’ he  devotes much of his attention and work to wood, a medium that he understands completely. Starting 1972 his works are exhibited in major  Art Galleries in Vancouver, Burnaby,  Surrey and Ottawa. In 1986 an important personal exhibition is organized by the City of Como and his works are shown in the prestigious “Broletto Hall” of the City of Como.  in 1995 his home town also organizes a show in the town Hall.  On his almost permanent return to italy in 1993, he  works at some important public sculptures among which a bronze door for the Church of SS. Cosma and Damiano in Villa Guardia, a Carrara marble scultpture representing a hand commissioned by the Founding members of an important Association for Disabled Children, a marble sculpture called “Symbiosis” located in the park of a Textile Company of Como. In 1966, for the inauguration of the new City Hall building of Villa Guardia, Trinca’s sculture called “the Three Graces” is placet in the main hall of the building.

Trinca’s works are permanently exhibited at the Heritage National Museum (Ottawa), the Exposion Gallery (Vancouver) and at the Simon Fraser University (Vancouver) where in 2001 a show was organized by the University (in that occasion Trinca donated a few of his sculptures to the University). In September 2002, the Italian Consulate in Lugano (Switzerland) organized a personal exhibition of his works.
